5.6.3 – DSP Card Inputs
There are four optically isolated inputs to the DSP card.
These inputs can either be sinking or sourcing and the
selection are controlled by a jumper (J11) on the DSP
board. The factory setting is sinking.
The CLR terminal is a fail safe input that will terminate
program execution and or motion if open circuited.
This
input must be active to allow auto-execution to occur
on power turn-on or if a RESET command is issued
.
The program that will be auto-executed is selected by
the input states of the SEL 4, SEL 2 and SEL 1 inputs.
Note: In Order for motion to occur, a CLR to COM
jumper is required.
Projects are loaded sequentially into the MX2000 con-
troller memory after an ERASE DIR command is issued
and are labeled projects 0 to 6.
